| PayBackTime |
|
PayBackTime is a simple perl/CGI interest loan calculator, similar to "VeryInteresting" and "AffordaBilly" but focused on determining how long it will take to pay off a loan or credit card, given a minimum payment, balance, and interest rate. The results will show the time it will take to pay off the balance with that monthly payment, number of payments, and the total interest the user will end up paying. For illustration purposes, it also shows the same data based on a bi-weekly payment of half the amount of the monthly payment. This is another very simple, yet nice educational tool for showing just how much only a few dollars a month can decrease the time to pay off a balance, and for showing just how much you pay for the privilege of using a credit card and paying the minimum payment. Most people simply don't think about how much they're paying, and this is a nice illustration. Students I've shown this to (and not just students, but most people) are often amazed at both the length of time it will take to pay the balance off, and by the amount of interest they will pay. PayBackTime is a blatant ripoff of the VeryInteresting payment calculator, also available for download from this site.

| Quadratic-o-matic |
|
Quadratic-o-matic is multi-platform compatible. Quadratic-O-Matic presents an equation in the form of Ax^2 + Bx + C = 0. You can fill in A, B, and C, and the program will show you the roots of the equation (what "x" is). Even gives you answers in terms of the imaginary number "i" if "B^2 - 4AC" is negative.

| The Fluid Flow Calculator |
|
This calculator is used to calculate pipe friction losses for straight piping handling water and water with varying percentages of ethylene glycol. The calculator uses an algorithm developed from the basic principles of fluid mechanics. The program is based on the Darcy-Weisbach equation, the Colebrook equation, and the Moody equation. The program is intended for use only on straight piping. The program does not include pressure losses due to elevation differences, or flow through fittings.
